(-harlotte, N. C., assignor to General 1 l'l leetric .lompany, a Corporation of New \ork. Filed Sept. 20, 1910. Serial No.

' understood that the various imil-11156151 511 Ilucnnn, a citizen of the-United States, residing at Charlotte, in the county of Meeklenhurg, State of North Carolina, have invented a new and useful Feeder Yoltage- Regulator, of which the following is a specitir-ation.

This invention-relates to a new and useful regulator for non-automatically compensating the voltage of an alternating current circuit and can be used. with equal facility on single or polyphase circuits and has for its object to actuate a-regulating transformer where the voltage has fallen or risen above the. desired point.

It has for a further ob'ect to provide a re nllator which is self adjusting to maintain a closed circuit whereby it becomes substantially impossible for the contact mechanism to come to rest between two adjacent points, that is, the circuit closer is at all tunes in exact engagement with one of thesoveral contacts.

It. further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accom anying drawings one form thereof whici is at iresent preferred by me, since the same has )een found inpractice to give satisfactory "and reliable results, although 'it is to be ties of which my invention consists (an be variously arranged and organized and that my invention is not limited to the preeise arrangement and organization of these lllfill'll'. mentalities as herein shown and described. Figure 1 represents a section of a voltage regulator embodying my invention, said section being taken on llllt'. m--n: of Fig. 2. Fig. 2 represents an elevation in partial sec tion of mynovel re nlntor. Fig. 3 represents a perspective 0 one of the parts shown in Fig. 1. f Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :--1 designates a casing or other suitable tank in which the.operatin parts of the mechanism are inclosed. 2 esignates a cover for the same which, in the present instance, serves as a E'E'DER vom emm support for a plurality of rods 3 preferably threaded and adapted to carry a suitable; transformer 4 of any desired step typel b'it-tititiiitifycontacts sfror' 't1i'i"tranS rormer. are suitably mounted on a support, such as a 'board 6 or the like, also carried by the; rods 8, said board having an opening 7 there-t through to permit the contacts on disk 8 to pass into engagement with the stationary contacts 5. This step transformer t and its contact mechanism are of any desired type, and I preferably show them herein operating in oil or the like, the level of which is indi-% cated at 9, whereby all the parts are sub-E merged in oil and are protected from the, outside. l

10 designates a shaft suitably jonrnaledl in the present instance, in the cover 2 and? carryin" thereon the contact carrying disk 8 and a so a worm wheel 11, which latter is in mesh with a worm 12 carried by a spindle 13 suitably mounted. 1

14 designates a dial suitably secured to the; -cover 2 and having thereon a plurality of,

index points 15 spaced apart and alined with; respect to the contacts 5 of the transformerl These index points 15 are respectively; ridden by an index finger 16 fixedly secnredl to the shaft 10 by a pin 17 or other suitablel fastening means, and it. will be apparent; that if the worm I2 is rotated asimilar move-i r'nent will be imparted to the worm wheeli 11, thus turning the shaft 10 and causing, the index finger 16 to move from one pointl to another as desired, thus showing position, of contacts on disk 8. Suitable stops 18; are provided to limit the movement of the-1 index fin er in either direction. 5 19 designates a.crank arm suitably se-i cured to the spindle 13 and carrying a eonnterweight 20 to which the operating handle 21 in the present instance 18 attached. It; will thus be noted, should the crank arm 191 be partially rotated in one direction or the other and released, that the weight. of the 5 eml thereof is sutlicient to return the same to normal position, that is, in the present instance in a vertical position, and thus shitting the worm wheel 1 1 so as to bring the index linger 11'' over one of the index points 15. The etlieiency of this arrangement will be appreciated when it is seen that the index linger It' is thereby prevented from stopping between any of the index points 15 and thus contacts on disk 8 will not stop between contacts 5, aml therefore no interruption of the circuit. is permitted.

2'. designates feed wires receiving current from any suitable source and delivering the same to the transformer as will be readily apparent.

In the operation of the device the parts are positioned as indicated in Fig. 1 "for any particular voltage, and should at any time the voltage fluctuate,- taking for example, a drop in voltage, the transformer may be an;faais'ata by resinag ee" "'s'pia'ule 1a" through the medium of the crank arm 19 so as to cause a shifting of the contacts on the jdisk 8 with respect tothe contacts 5, wherel y the transformer isimmcdiately' regulated for the change in the voltage.

embodics the features of advantage enumerated as desirable in the statement of the ml have. in the. present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be ,undcrstood thatthe same is susceptible of modification in various particulars without leparting from the spirit or scope of the invention or sacrificing any of its advanta cs. Having thus described my invention,w int I claim as new and desire to secure by Leters latcnt, is:- 1. In a device of the character stated, a current controlling device, a plurality of contacts for said controlling device, a shaft earryin one set of said contacts, a spindle rotatabiy mounted adjacent said shaft, gearing between said spindle and shaft, a crank arm for manually ,operatin said spindle, and a counterweight carrie It. will lie-noted, if for any reason he.

vised a novel transformer regulator which vention and the above description, and while- I (if the cliaracterl stated. a current-controlling device comprising a pluralit-y of stationary contacts and a movable contact, a shaft carrying said movable contact, a spindle rotatably mounted adjacent said sha t, means between said'spindle and shaft to shift said movable contact to either of the next adjacent. staticnary contacts during' one revolution of said spindle and gravity controlled means for causing said movable contact to positively engage said adjacent contact.
